In the modern spirits landscape, "authenticity" is often a marketing term tossed around as loosely as a wedge of lime in a cheap Margarita. But for McCauley Williams, the founder of Alma del Jaguar tequila, the pursuit of an authentic spirit wasn't just a business plan - it was a personal reclamation project born out of a professional crisis.
The story of Alma del Jaguar is not the typical corporate "lifestyle brand" launch. It is a tale that began in the "law mines" of corporate mergers and acquisitions, traveled through a devastating boardroom takeover in the bourbon world, and finally found its soul in the high-altitude agave fields near Arandas. Today, the brand stands as one of the fastest-growing craft tequilas in America, winning over aficionados and new fans not through celebrity backing, but through a rigorous commitment to quality, innovation, and a higher mission: jaguar conservation.
The "Jailbreak" from the Law Mines
Williams began his legal career as a mergers, acquisitions, and securities law specialist. But his entrepreneurial career started much, much earlier, selling candy out of his locker in fourth grade. He later imported commercial drones, and also ran a mobile beer vending business.
That commitment to the hustle was not particularly well matched with the requirements of corporate law. Williams referred to his time at the firm as "the law mines," a grueling period of paperwork and billable hours that he hoped would eventually lead to a "jailbreak" into full-time entrepreneurship.
His real entry into the spirits industry came when his firm was hired to liquidate a failing vodka distillery. Seeing an opportunity where others saw failure, Williams raised the capital to buy the operation and pivot it into a bourbon business. Over the course of 4 years, the brand saw explosive success, becoming one of the fastest-growing bourbon brands in the country by 2021. However, the victory was short-lived for Williams; after a series of board room disputes, Williams was voted out of the company he had built.
Due to legal complexities that arguably barred him from making American whiskey for a period of time, Williams turned his eyes toward Mexico. He possessed a newfound knack for building craft spirit brands but realized he knew nothing about making them from agave.
He rebuilt from scratch - literally starting with a new laptop and a cell phone after turning in his corporate technology - and headed to Mexico to find a distillery that could match his vision.
Finding the Heart of the Jaguar at NOM 1414
Finding a production partner was an arduous journey of knocking on distillery doors and visiting dozens of underwhelming industrial operations. The breakthrough happened purely by happenstance at a Guadalajara bar called Desestrés. A conversation with the bar's owners led to a late-night recommendation: the Vivanco family.
At NOM 1414 (Sergio Vivanco y Associados), Williams found a different kind of partner. Unlike the industrial sites he had toured, the Vivancos focused on the high-touch aspects of production - legacy, soil, and a winemaker’s approach to agave. "I immediately fell in love with the Vivancos and their operation," Williams recalled, noting that the Vivancos' focus on single-estate agave was exactly the level of quality he was seeking.
Today, Alma del Jaguar is one of the few brands that is truly vertically integrated. They source single-estate agave, and every component of the product - down to the recycled glass and labels - is manufactured locally in Mexico. "Every single component is recycled material sourced from Mexico," Williams says.
The Science of the "Hook": A Dual-Yeast Revolution
For the Tequila Report reader, the true differentiation of Alma del Jaguar lies in the chemistry of the fermentation. Williams applied his experience in spirits maturation to create a flavor profile that he describes as having a perfect "hook" on the palate.
Alongside Master Distiller Sergio Cruz and tequila expert Adam Fodor, the team developed a unique two-yeast blend. While many brands use a single strain for consistency, Alma del Jaguar utilizes a ratio of 80% wild yeast and 20% champagne yeast.
Fermentation of Alma del Jaguar Tequila
Through trial and error, they discovered that 100% wild yeast produced a beautiful high-proof spirit but "fell flat" on the front palate when diluted to the standard 40% ABV. The addition of champagne yeast provided a necessary "sweetness at the beginning" to engage the palate immediately, while the wild yeast retained the earthy, terroir-driven notes and a long-lasting finish.
"Ideally, we want a spirit, no matter what category you're in, that is highly engaging up front," Williams explains. "It’s like an Instagram video when you're scrolling. You have to have that hook that engages you, something in the middle that keeps you going, and then some sort of close that leaves a lasting impression"
The Barricas Series Playground
While the core Blanco and Reposado are the brand's commercial foundation, the Barricas Series is where McCauley Williams lets his inner entrepreneur "mess around in the garage" with exotic casks. The series sold out instantly, so if you see one around, grab it.
Exotic Finishes: The series includes limited releases aged in Mizunara Oak from Japan, Calvados (apple brandy) casks from France, and Vino de Naranja (orange wine) casks, and a Pearwood unicorn barrel sourced from a French furniture maker.
Round 2 Coming: Look for future barricas projects involving Ukraine Ice Vine barrels—sweet dessert wine casks sourced from the conflict region—and Japanese Sakura (cherry wood).
The Jaguar Legacy: Conservation as a Core Mission
For Williams, the jaguar is far more than a striking visual on a bottle; it is a profound link to his family's history and a driving force for the brand's existence. The brand was born during a personal and professional "rock bottom" for Williams, who sought a higher mission beyond simple commercial success. This led him to his uncle, who had dedicated his life to wild jaguar conservation in Mexico as the co-founder of the Northern Jaguar Project and Reserve. "I would love it if we could figure out a way to link your jaguar conservation with my entrepreneurialism," Williams proposed during the brand's early stages.
Today, Alma del Jaguar (which translates to "Soul of the Jaguar") operates with a formal commitment to donate 10% of its profits to wild jaguar conservation groups. While Williams acknowledges the brand is still an emerging company, he has expanded this mission through purpose-driven awareness campaigns. To date, the brand has raised an estimated $40,000 directly for conservation, with an indirect benefit reaching several hundred thousand dollars through films and events. By producing documentaries and sponsoring wildlife photographers, the brand champions big cat conservation in the critical U.S.-Mexican borderlands.
Quality, not Gimmicks for Alma del Jaguar
"We want to be always known for producing the highest quality, with great branding, and winning kind of on the merits, not on the gimmicks," Williams emphasized. By controlling the supply chain and refusing to use additives, the brand has positioned itself as a permanent fixture in the craft tequila world.
For Williams, the ultimate test is a simple one: "I would probably serve all of our products to an esteemed guest in my own home, and not every brand owner can say that." Whether it is the staple Blanco or the rare Pearwood aged expression, Alma del Jaguar is proving that a brand born out of a professional "low point" can reach new heights by simply being so good it can’t be ignored.
The Expressions of Alma del Jaguar
Blanco (40% ABV): The flagship expression featuring the 80/20 wild and champagne yeast blend. Designed to be exceptional in cocktails but also sips beautifully neat, it balances Highland agave sweetness with earthy, brine-forward complexities.
Nocturna (High Proof Blanco): The "unplugged" version of the brand. Originally a wild yeast project that Williams loved for its raw power, it is bottled at a higher ABV to retain the "magic" of the wild fermentation that can sometimes be lost at lower proofs.
Reposado: Aged using a double-barreling process that utilizes both American and French oak. Williams brings his bourbon expertise here, using whiskey techniques adjusted for the delicate nature of agave to ensure the oak complements rather than overwhelms the spirit.
Añejo: The latest expression is a small-batch release that combines three individually aged lots in American and French oak barrels. There's a creamy mouthfeel here along with hints of baking spices, citrus, and vanilla. It is lighter and more agave-forward than a typical añejo.
Harmony Añejo (The Tequila Report Special Batch): A truly unique collaboration born from a moment of creative indecision at the distillery.
While selecting barrels for this special batch, the team was torn between an American oak standout (aged 28 months) and a French oak standout (aged 21 months).
At the suggestion of The Tequila Report co-founder Maddie Jager, the team decided to blend them. The result is a beguiling, high-proof harmony of butterscotch, caramel, and raspberry, proving that sometimes the best way to find a soul is through a perfect partnership.

Alma del Jaguar represents a rare intersection where high-level spirits science meets a gritty, boots-on-the-ground commitment to conservation.
By combining the Vivanco family’s multi-generational agave expertise with a radical devotion to Mexican-only sourcing and a significant financial pledge to the wild jaguar, McCauley Williams has built a brand that succeeds on its own merits rather than celebrity influence.
Ultimately, the spirit serves as a liquid proof of concept: that a modern tequila can be both technically superior and a powerful vehicle for protecting the wild heart of Mexico.
